ABB SF810INT-LOS-UV-T-L UV Flame Scanner

Description

The ABB SF810INT-LOS-UV-T-L is a high-performance UV flame scanner from the Uvisor™ SF810 series. Designed for line-of-sight (LOS) burner configurations, it uses a solid-state UV sensor to detect flame presence and quality with exceptional reliability. Ideal for wall-mounted, corner-fired, down-fired, and cyclone burners, it ensures safe and efficient combustion monitoring in utility and industrial boilers.
